Once you are connected to Mailchimp, you will then find a Mailchimp Action field in the Submission area in the Form Options panel of an individual form.
To get your form submission contacts to be automatically added to Mailchimp, you need to do a few things.
1. Choose the Create/Update Contact Action.
2. Choose a List to send them to.
3. Optionally, enable the Double Opt-In option.
4. Map the fields in your form to the fields in your Mailing List.
Towards the bottom of the Submission Panel you will see a notice that you are connected to Mailchimp. Directly under this, is the Mailchimp Action option, which has two options – None, and Create / Update Contact. If you select that second option, a Mailchimp List option will appear below. Here, choose the Mailing List you want to add the contacts to.
Under this, there is a Double Opt-in option, which if enabled, will mean that everyone who submits the form will receive a follow-up email with a confirmation link to verify their subscription.
Finally, under this, you will see a range of Mailchimp mapping options. There will be one for each Form Field, with a mapping option beneath it. For this to work, you must have an Email field in your form.
In each field you want mapped, select the corresponding Field in your Mailchimp account for it to be mapped to. By default, fields will show Automatic Field, and will attempt to map fields automatically by matching labels, but clicking on this will reveal a dropdown list of both common and other Mailchimp fields, and here you can specifically map each email form fields to the specific Mailchimp field, as seen below.
Once you are done mapping fields, just save your changes, and the next time someone submits the form, their contact details will be added (or updated if their email address is already listed in the Contacts) in your Mailchimp account. The advantage of this, is that you then have access to the full range of marketing actions for each contact in your Mailchimp account. This is a powerful feature for users of Avada and Mailchimp, so check it out.
